This was unacceptable to Mario Sinacola and Sons (the Contractor) stated that they would not be able to provide a warranty on the material unless sand was used as fill around the conduit. This was unacceptable to the AECOM (Engineer of Record EOR) and the City of Fort Worth (Owner). Pat Buckley with the City of Fort Worth was concerned about the specified backfill and the close proximity of the conduit trench to the future airport perimeter road . The parties agreed to use flowable fill (lean concrete) as a backfill material instead of sand. The Owner will receive a product superior to the originally specified product by using flowable fill because the conduit will be better protected. The unit price of $6.87 /Linear Foot submitted by the Contractor equates to $10.41 L.F for flowable fill with credit of $3.87 L.F. for original #57 crushed aggregate and Prime Contractor mark up of 5% $0.33 L.F . which was verified to be fair and reasonable by survey of local concrete/flowable fill suppliers . Bid Item 28 Install Gabion Mattress Complete In-Place Extend Quantity The engineered quantity did not accurately reflect the quantity of Erosion Control Gabion Mattress portrayed in the drawings. The additional quantity will reconcile that difference. Bid Items 29, 30 and 32 Conduits 1 W' innerduct, 1 Yz" conduit and 4" conduit installed The quantities for these items were increased per RFl-13 that directed the Contractor to realign the duct bank from the south side of the Utility Corridor to the north side, increasing the length by 88 L.F. per conduit. Bid Item 34 Electrical Pull Box 48" x 48" Installed The quantity for this pay item was increased per RFl-18, Verizon Pull Boxes were to be installed every 1000'. The original plans did not show a Verizon Pull Box installed between Sta. 21+75 and Sta. 38+90. The Contractor was instructed to add a Verizon Pull Box at Sta. 30+20. New Bid Item 36 Export Unsuitably Material (Rock) This item was added per RFl-14, Contractor was directed to remove unsuitable rock from imported fill material and haul off site. Bid Items 16 and 18 Silt Fence and Rock Check Dam These Items were increased to provide more effective erosion protection for new culverts. Add Fourteen Days to the Contract The Contractor submitted a request for an additional 30 days to the contract. He offered the justification that the time between Contract Bid Opening, Contract Award, and Contract Notice to Proceed was in excess of the maximum time allowed in the Contract. The Contractors request claimed that this caused a "' .. ~ ' loss of their ability to use a planned source of suitable embankment material on this project. This in turn caused the Contractor to have to seek another source which claimed additional days were lost. After careful review of the language in the contract we found an ambiguity regarding the maximum time for bid evaluation. 1 The contract was silent on the amount of time between Contract Award and Contract Notice to proceed. In light of the ambiguity and silence in the Contract, and in an effort to reach a compromise without burdening the City of Fort Worth with additional overhead costs, we negotiated an extension of 14 days to the contract. Furthermore, we clearly defined that Contract Substantial Completion as the installation of the embankment and conduit according to the Specifications. We excluded complete acceptance of the seeding and sodding as part of Substantial Completion because this portion of the work will not require full time inspection by the City of Fort Worth. DELETIONS TO CONTRACT Bid Items 31 and 33 Conduits 2" PVC Installed and Conduit 6" Directional Bore These bid item quantities were reduced when franchise utility provider Qwest informed AECOM (Design Engineer) that they would not be using this utility corridor. 1 See Addendum 2 Comprehensive Notice to Bidders paragraph 12; Addendum 2 Special Provisions Paragraph 30- 02; FAA Special Provisions Section 30 paragraph 02. 1v1~\....
